Title: Linear stepping motor
Inventor: OSAWA MASAHIRO
IPC: H02K41/03
Filed: 1987-09-02
Abstract: PURPOSE:To increase the degree of accuracy for gap dimension by dividing and forming moving element, placing the graphite powder on the part of magnetic insulation in advance to heat and perform alloying, thereby lowering permeability. CONSTITUTION:A permanent magnet type linear stepping motor is formed on a closed magnetic path in the flux from the permanent magnet returns to the original permanent magnet passing by a moving element yoke 13, a rail and a moving element yoke. The moving element yoke 13 has the magnetic poles 6a-6d, and a plurality of magnetic teeth 8a-8d are formed on each of the ends of the poles. The moving element yoke 13 converts an insulating area 14 into a non-magnetic or lowers significantly permeability in comparison with the other part. Therefore, the powder as a source of carbonizing is placed on the surface of a material such as a silicon steel plate wherein the laser beam is radiated and scanned to perform instantaneous heating and melting locally, and a partial high carbon area is formed thereby. Accordingly, high degree of accuracy for relative position and gap dimension is realized.

Title: Optical information recording/reproducing device
Inventor: NISHINOMIYA MASANOBU
IPC: G11B7/125
Filed: 1986-09-18
Abstract: PURPOSE:To ensure the stable recording/reproducing operation regardless of the temperature change by detecting the radiated light quantity of compare it with the reference voltage for control of the reproducing light source current and then controlling the recording light source current in response to said reproducing light source current. CONSTITUTION:In a reproduction mode where a switch 7 is kept ON, the light radiated from a semiconductor laser 1 is received by a photodetecting element 2. Then this photodetecting output is compared with the reference voltage by a comparator 4 and the driving current of a current source 6 is controlled. Thus the quantity of the light radiated from the laser 1 is kept at a fixed level. The driving current changing by temperatures is detected by a current detecting circuit 8 and latched by a latch circuit 10 after D/A conversion. The latch contents corresponding to the temperature change undergo D/A conversion and the driving current of the laser 1 is controlled via recording power supply 12 in a recording mode set by an ON state of a switch 13 after reproduction. As a result, both reproducing and recording radiated light quantities are kept at a fixed level respectively despite the temperature change. Then the stable recording/reproducing operation is ensured even with the temperature change.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a hinged cap having a hinge mechanism which functions favorably in the way the cap works with a snap and as regards the way the cap is handled and in being durable. SOLUTION: A hinge mechanism 16 of a cap 10 of a container consists of a three-piece hinge composed of a hinge body 36 by which an over-cap 14 is held swingably in relation to a cap skirt 12 and a pair of elastic pieces 38 placed on both sides of the hinge body 36. The ends of the elastic pieces 38 are jointed respectively with the cap skirt and the over-cap in an arc or straight line along their peripheries. When the cap is opened 180 deg., the elastic pieces assume the shape of approximately an arc between the cap skirt and the overcap and become thicker the nearer the position under consideration is to the ends. Since the thickness of the elastic pieces is made larger on the side closer to the ends where stress concentration is liable to occur, this constitution serves to even out the distribution of stress.

Abstract: PURPOSE:To rustproof-treating magnetic metal powder providing graphite coating on the powder surfaces, by bringing the metal powder into contact with hydrocarbon gas or water gas and making them react. CONSTITUTION:Powder of Fe, Co, Ni, or alloys of these with a particle diameter of 0.5mu or smaller is used. When a mixed gas of Co and H2 is used, graphite coating effective for preventing the oxidation is formed on the surfaces of the metal powder by bringing the powder into contact under 150-400 deg.C. Or, using methane or ethane, etc., the metal powder is brought into contact under 300-500 deg.C in an H2 current. It is appropriate that the amount of graphite effective for preventing the oxidation should be in the range of 0.5-15wt.% to the metal powder. The magnetic metal films obtained by this method have merits that the lowering of the saturation magnetization sigmaS is very little and the durability for preventing the oxidation is sufficient owing to the fine graphite coating.
